Answer:
x=6 and y=2
Step-by-step explanation:
3x+5y=28
−4x−5y=−34
Add these equations to eliminate y:
−x=−6
Then solve −x=−6 for x:
−x=−6
(Divide both sides by -1)
x=6
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
3x+5y=28
Substitute 6 for x in 3x+5y=28:
(3)(6)+5y=28
5y+18=28 (Simplify both sides of the equation)
5y+18+−18=28+−18 (Add -18 to both sides)
5y=10
(Divide both sides by 5)
y=2

Answer:
0 = x⁴ -x³ -9x² -11x -4
Step-by-step explanation:
Each root r contributes a factor of (x-r). The factored form of the polynomial of interest is ...
0 = (x +1)³(x -4)
0 = (x³ +3x² +3x +1)(x -4)
0 = x⁴ -x³ -9x² -11x -4
